Los dep\u00f3sitos de arena y grava que se encuentran en las playas o en los r\u00edos y arroyos est\u00e1n formados principalmente por granos de cuarzo (di\u00f3xido de silicio, SiO2). La meteorizaci\u00f3n de rocas como el granito forma estos granos de cuarzo. En el proceso de meteorizaci\u00f3n, los minerales m\u00e1s blandos y d\u00e9biles del granito (como el feldespato) se desintegran. El cuarzo, m\u00e1s resistente, acaba reduciendo su tama\u00f1o, pero no se descompone qu\u00edmicamente. Con el tiempo, estos granos de cuarzo se acumulan en r\u00edos, arroyos, deltas y playas.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n

Los m\u00e9todos de extracci\u00f3n de arena industrial dependen del tipo de yacimiento. Los yacimientos no consolidados se extraen con cargadoras frontales, rascadoras o bulldozers. El material se excava y empuja hasta un punto central. A continuaci\u00f3n, el material de calidad mineral se carga en un cami\u00f3n con un equipo est\u00e1ndar de movimiento de tierras, desde donde se env\u00eda a un dep\u00f3sito o a una planta de procesamiento.<\/p>\n

Una draga hidr\u00e1ulica utiliza un tubo de succi\u00f3n para excavar la arena, que se bombea a trav\u00e9s de una tuber\u00eda hasta las pilas de compensaci\u00f3n o directamente a una planta de procesamiento. El canal o dep\u00f3sito de est\u00e9riles se excava y se coloca en una pila de acopio. El material de calidad mineral se carga en camiones para su transporte a una planta de tratamiento.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n

La arena y la grava se utilizan en la construcci\u00f3n de carreteras, para mezclarlas con el asfalto, como relleno en la construcci\u00f3n y en la producci\u00f3n de materiales de construcci\u00f3n como bloques de hormig\u00f3n, ladrillos y tuber\u00edas. Tambi\u00e9n se emplea para fabricar tejas, se utiliza en carreteras heladas en invierno, para balasto ferroviario y filtraci\u00f3n de agua.<\/p>\n

La arena y la grava industriales se utilizan para fabricar vidrio, como arena de fundici\u00f3n y como arena abrasiva.<\/p>\n

Para algunas aplicaciones, es el contenido de s\u00edlice (cuarzo) de la arena lo que la hace tan valiosa. El s\u00edlice es necesario para fabricar productos como el vidrio. Adem\u00e1s, las propiedades f\u00edsicas de la arena, en particular su propiedad abrasiva, la hacen \u00fatil para la tracci\u00f3n en carreteras y v\u00edas f\u00e9rreas heladas, y para el chorro de arena.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n
